Abstract (en)

[origin: EP3376066A1] Provided is a dual-clutch transmission, including a dual-clutch device 20; a first primary gear train 41 for transmitting power from a first input shaft 31 to a subsidiary shaft 34; a second primary gear train 42 for transmitting power from a second input shaft 32 to the subsidiary shaft 34; a plurality of output gear trains 51 to 53 rotatably provided on an output shaft 33; and a synchronization mechanism 60 for synchronously joining the output gear trains 51 to 53. Step ratios upon gear shifts performed by only clutch change are set to be smaller than step ratios upon gear shifts performed by both clutch change and gear change.
